So you have a drawing view of maybe an odd shaped object and you wish to set it horizontal or vertical to a known edge for better reference. Sure you can rotate the view, but entering 22.33871842 degrees may still not be exactly horizontal. So how do we do it?
Well ok then, select the line to be the horizontal reference and go to the Tools drop down menu.
Once you have picked the orientation SOLIDWORKS will rotate the view so that is the horizontal edge.
